Those can't possibly be your actual IPFW rulesets-- the "http://" strings in 
the middle don't exist in the output from "ipfw -a l".

It's unclear whether you are working on a client machine or box intended as a 
firewall.  It's likely that you should start with the "open" firewall ruleset, 
and experiment from there, confirming that FTP access via the proxy works 
properly, HTTPS access, etc.

If you still have problems without any firewall rules in place, those will need 
to be resolved before you have any realistic chance of getting a working IPFW 
ruleset going.

It might also be the case that hanging trying to do FTP data means a PMTU 
problem, see whether "ifconfig vr0 mtu 1400" helps.
